Aluminium lanterns are strong and slim, but they still rely on gaskets, cappings and seals that wear. Send photos from Denton (M34) and we'll tell you which it is — with the price agreed in writing before any work.

What you might be seeing
- Leaks at bars or ridge
- Cappings lifted or rattling
- Chalky or chipped powder coat
Why it happens
Worn gaskets
Gaskets do the weatherproofing; they harden and shrink with age.
Finish damage
Scratches and chips expose bare metal; coastal air speeds up corrosion.
About Denton and the M34 area
Damp, mild winters keep moss and algae growing on flat roofs and lantern frames, which holds water against seals and blocks weep slots. Regular clearing makes a real difference in wetter areas.
In built-up areas, access is often the hardest part of the job — through the house, over a neighbour's roof, or with parking restrictions. We plan access in advance and price any tower or scaffold into the quote.
We cover Denton as part of Greater Manchester, about 5 miles from Manchester.
Neighbouring places we cover include Hyde (2 miles), Dukinfield (2 miles), Droylsden (2 miles).
How much should it cost?
Typical range: £195–£695 ex VAT, which is £234–£834 with VAT, per lantern. Towers or scaffold, where needed, are priced into the quote. Your fixed price is confirmed in writing before any work starts.
Do you need permission in England?
Straightforward repairs — resealing, gaskets, cappings, eaves and like-for-like parts — don't normally need building regulations approval in England. Replacing the whole lantern or enlarging the opening is different and falls under the Building Regulations 2010; we confirm in writing which route applies before any replacement. Listed buildings need listed building consent from the local council for alterations, and conservation areas can have extra controls; like-for-like repairs are treated differently from changes, so check with the council's conservation officer first.
